INNER JOIN MEANS, IF THE JOIN CONDITION SATISFIES THEN ONLY

RECORDS WITH MATCHING AND NON MATCHING RECORDS.

if it wrong means please mail me chandranmca2007@gmail.com

Answer / sehaj

INNERJOIN-GIVES THAT RECORDS THAT ARE PRESENT IN BOTH THE TABLE
OUTERJOIN-GIVES THAT RECORDS WHICH ARE PRESENT AND ALSO
WHICH ARE NOT PRESENT IN ONE OF THE TABLE.

INEERJOIN-REQUIRES LESS PROCCESING TIME.
OUTERJOIN-REQUIRES THE MAX PROCESSING TIME AMONG ALL THE
KIND O JOINS.
